Fig. 1: Structural characterizations and of Co6Ni4.
From: Revealing and modulating catalyst reconstruction for highly efficient electrosynthesis of ammonia
a TEM image of Co6Ni4 and (b–d) corresponding HR-TEM images. The inset in (a) shows the SAED pattern. e TEM-EDS line-scan of the region marked with white arrows in the inset. f AC-HAADF-STEM image and the corresponding elemental mappings of Co6Ni4. g Co K-edge and i Ni K-edge XANES spectra of Co6Ni4 and the references. h, j The k3-weighted Fourier transform of the k-function from Co K-edge and Ni K-edge EXAFS, respectively. Source data for the figures (e, g–j) are provided as a Source Data file.
